On the pyrophytism in the Mediterranean area
2015
Authors briefly present some observations and reflections on the “seeding strategy” of some plant species (Cistus spp., Cistaceae, in particular) in the Mediterranean area in relation to fire: they conclude it does not seem a specific adaptation to wildfires (as suggested in a relevant part of the recent literature), but a generalistic adaptation to open, high energy and variable habitats with aleatory fluctuations. The difference is important both for theoretical and applied aspects, e.g. for the correct management of Cistus species and of other Mediterranean species and habitats. Fire is undoubtedly a major ecological factor in the Mediterranean area. Many botanists have postulated the re…
Biological properties of carotenoids extracted from Halobacterium halobium isolated from a Tunisian solar saltern
2013
Abstract Background Bioactive molecules have received increasing attention due to their nutraceutical attributes and anticancer, antioxidant, antiproliferative and apoptosis-inducing properties. This study aimed to investigate the biological properties of carotenoids extracted from Archaea. Methods Halophilic Archaea strains were isolated from the brine of a local crystallizer pond (TS7) of a solar saltern at Sfax, Tunisia. The most carotenoid-producing strain (M8) was investigated on heptoma cell line (HepG2), and its viability was assessed by the MTT-test. The cells were incubated with different sub-lethal extract rates, with carotenoid concentrations ranging from 0.2 to 1.5 μM. Antioxida…
Paul Bert et l'instruction publique
2001
Paul Bert (1833-1886) a été professeur de physiologie à la Sorbonne, membre de l'Académie des sciences, député républicain, ministre de l'Instruction publique et des Cultes du gouvernement Gambetta, et résident général au Tonkin et en Annam. Il a participé à tous les degrés de la réforme de l'enseignement, et a surtout été avec Jules Ferry, le fondateur de l'école gratuite, laïque et obligatoire. Partisan de la laïcité, il a lutté, au nom de la liberté de conscience, pour la suppression de l'enseignement religieux et l'introduction de l'instruction civique et morale. Ce combat de la laïcisation a été en même temps celui mené contre le cléricalisme. Il a également voulu fonder l'école de la …
Human cytomegalovirus (HCMV)-specific CD4+ T lymphocyte response in AIDS patients with no past or current HCMV disease following HAART.
2003
Abstract Background: The incidence of Human Cytomegalovirus (HCMV) end-organ disease has dramatically decreased since the implementation of highly active antiretroviral therapies (HAARTs), but the precise immune mechanism whereby HCMV is controlled remains to be elucidated. Objectives: To investigate the effect of (HAART) on CD4 + T-cell immunity to HCMV in AIDS patients with no past or current HCMV disease. Study design: Seventeen patients were prospectively examined for CD4 + (CD45RO + and CD45 RA + ) T-cell counts (flow cytometry), HIV RNA load (Amplicor HIV test), HCMV leukoDNAemia and HCMV DNA in urine (nested PCR), lymphoproliferative response (LPR) to HCMV, phytohemagglutinin (PHA) a…
Application of a 5-bromo-2′-deoxyuridine ELISA for measuring the lymphoproliferative response to human cytomegalovirus in HIV-1-infected patients
2002
Assessment of the lymphoproliferative response to human cytomegalovirus (HCMV) may help to identify human immunodeficiency virus (HIV)-1-infected patients at high risk of developing HCMV end-organ disease. The tritiated thymidine ([3H]-TdR)-incorporation assay is the gold standard for measuring lymphoproliferative responses, though it is unsuitable as a routine laboratory procedure. An alternative non-radioactive technique, a 5-bromo-2'-deoxyuridine (BrdU) enzyme-linked immunosorbent assay, was applied for measuring T-cell proliferation in response to HCMV. Stimulation of either 1 x 10(5) or 5 x 10(4) peripheral blood mononuclear cells (PBMCs)/well with 10 PFU/well (before inactivation) of …
Increased susceptibility of complement factor B/C2 double knockout mice and mannan-binding lectin knockout mice to systemic infection with Candida al…
2008
Candida albicans is the major cause of systemic fungal infections in immunocompromised patients. We investigated the susceptibility of mice deficient in complement factor B and C2 (Bf/C2-/-), C1q (C1qa-/-), and mannan-binding lectin (MBL)-A (MBL-A) and MBL-C (MBL-A/C-/-) to systemic infection with C. albicans. Animals were infected i.p. with 10(8)C. albicans blastoconidia and monitored for mortality. Bf/C2-/- mice showed high mortality (over 90%) within the study period of 3 weeks. In contrast, mortality in C1qa-/- mice was below 15% whereas that of MBL-A/C-/- mice was 40% (P0.001). Intravenous infection of mice with 8x10(5) blastoconidia resulted in the same trend with Bf/C2-/- mice being …
Una ricerca interculturale in Sicilia: l'innamoramento vissuto dagli adolescenti tunisini nati a Mazara del Vallo
2011
Si presenta una ricerca avviata nell’autunno del 2009. Il problema dell’educazione affettiva degli adolescenti emerge quando avviene il primo innamoramento. Tale fenomeno mostra come sia andata fino a quel momento l’educazione dei sentimenti e lascia presupporre che cosa bisogna ancora fare per portarla a compimento. Si è voluto indagare, sia pure con uno strumento che non scava in profondità ma si accontenta della sincerità delle risposte, il modo in cui gli adolescenti tunisini nati in Sicilia vivono il fenomeno del primo innamoramento e i cambiamenti che tale fenomeno determina negli adolescenti che lo vivono e nel loro più immediato intorno sociale. Si espongono i risultati relativi agl…
Le dimensioni del ponte e la suggestione di TUNeIT
2016
Prendendo spunto dal profilo scientifico del Prof. Enzo Siviero, il breve contributo riassume i significati del sostantivo "ponte" e si ricollega all'esperienza di cooperazione internazionale del Progetto APER, finanziato dal Programma Italie-Tunisie 2007-13.
